Re: [ccp4bb] Atom labels in PDB file for Refmac

Thanks to all who answered - and so fast! - MET residues should become MSE (i.e. Se-MET instead of S-Met) - ' SD ' atom name should become 'SE ' - remove the columns 77-80 I had changed S to SE and that's fine Simply using an editor I changed the pdb file - and it works!! Thanks again, A

Dear Anita, Selenomethionine should be named MSE. The residue will show as HETATM, rather than ATOM, and MSE should be used consistently (SEQRES, HELIX, etc.) for the appropriate residues. I do not know what various software packages do with MSE but it occurs frequently so I would be

Hi, - MET residues should become MSE (i.e. Se-MET instead of S-Met) - ' SD ' atom name should become 'SE ' - remove the columns 77-80 - run PDBSET to let it re-generate columns 77-80 again. So something simple minded like % grep "^CRYST1" your.pdb > tmp.pdb % egrep "^ATOM|^HETATM" y

Dear all, This question may have been asked before, but I cannot find an answer in the recent ccp4bb archives - sorry! I am using an SeMet-protein data set as my native protein, since it diffracted to high resolution and should give all the information I need. I would therefore like to in
